This is odd because I am reading Finding Your Own North Star by Martha Beck and she goes into a very good distinction between the two. I would like to quote her from the book.

"(People who lived for mere pleasure, instant gratification, were called Sybarites, and you'd better remember that, because there will be a quiz in twenty minutes.) Hedonists believed in living for happiness, but they also believed that, due to our basically good inner nature, we can be truly happy only if we live moral lives, complete with integrity, compassion, and sometimes self-sacrifice.

joaquinlean: Did you get your definition of hedonism from the book "Finding Your Own North Star"? I can't find the idea of basic goodness in what I have read about hedonism. Have I not read enough or has Martha Beck inserted some of her own ideas in the definition? It could be either way. I am here to learn.

In any event I am convinced of basic badness so I am totally from another school. "In Adam's fall, we sinned all," is not a direct quote from the Bible. It is more complex than that.

In philosophy there are several types of hedonism.
1- the good is the most immediate, most intense, and perhaps the longest lasting pleasure. For me.
2- a different version lists the forms and types of pleasure, which may include intellectual and artistic pursuits, along with and usually ahead of sensual pleasure.
3- the greatest pleasurere and happiness for the most people for the longest time. Defining the words yet remain. Party schools vs academic campuses.
4- Kant's "categorical imperative": So act that you could will your actions be done by all. Or if everyone acted as you do, would the world be a better place? (define "better."
